W WM ATTORNEY Patented Mar. 6, 1945 UNITED I STATES PATENT -OFFICE' TYJEEWRITER CARTON Leon Frank'Perkins, Wayland, Mass. deputation retai s 1, 1943, Serial No.474,317 f rearms. I (craze- 14) One object of my invention is to provide a carton to pack and transport a typewriter in that ing it in, and likewise be readily-withdrawn by merely lifting it out. v

Still another object is to make said carton in transportation with less effort requiredto pack the typewriter therein than has heretofore been necessary.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished bya construction, combination and arrangement of parts such as is disclosed by the "drawings and specification. The nature of the invention is'such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to said disclosure; but am entitled to. all such changes therefrom as fallwithin the scope of my claims.

In the drawings:

Figure 1 is an exploded, perspective view of different parts constituting my typewriter carton.

Figure 2 is a plan view of the typewriter supporting board used in said carton.

Figure 3 is an elevational view of the longer side of my carton, partl in section, showing a typewriter after it has been inserted into said carton, the whole being in loading position, which is upside down, with the bottom covers open.

Figure 4 is the same elevational'view as Figure 3, but showing the shorter side of my carton, partly in section, with all covers closed.

As illustrated, I show an outside box of usual construction made of heavy cardboard material that has four outside walls l0, bottom cover pieces H and top cover pieces I2. For further reinforcement a separate top piece 13 is placed under said top cover pieces l2.

Spacedly fitting within said outside box is a rectangular tube M which has four sides Ma.

' This invention relates to interchangeable type- U writer cartons.

I simple and inexpensive in construction which will I serve its purpose to hold and protect a typewriter At'one end of said four sides Ma flaps or flanges l5 are formed by scoring and then bending over part of each said sides l4a to make said flanges [5. The cross-sectional area of said tube including said flanges l5 when lying flat exceedsthe space within said outside box so that the flanges have to bear diagonally against the side walls ID of the outside box. A space is left all the way around between said tube sides Ma and said outside box Walls l0, and said flanges l5 fill in this space at one 'end extremity of said tube 14 and make a tight pressure-fit so that the tube is firmly held'in' position. Since the material is sufficiently flexible to bend without breaking, such as heavy cardboard,'the joints, resulting where the flanges are bent are flexible. The effect is that when said tube I4 is inserted into said outside box and pushed downwardly said flanges I5 yield from their normal position sufiiciently to permit said tube It to slide down, although contact with said outside walls H] is maintained. The pressure contact of the flanges 15 makes the fit of the tube in the outside box a tight one. In withdrawing said tube l4, it is merely lifted out.

A typewriting' supporting board l8 flts within said outside box fairly snugly, extending across all four of the tube sides Ma and to said walls 10. It is preferably made of three-plyicardboard with the grain of the two outside cardboardsheets running in the same direction and the grain of the middle sheet running at right angles thereto.

This supporting board or base It .is provided with a number of sets of holes, depending upon how many different makes of typewriters it is prepared to receive. I have shown it with four sets of holes to receive four different typewriters, although one pair or two of the holes are adapted to receive two difierent typewriters. Typewriters have screw-threaded holes in their base to receive the screws that hold the rubber feet, or

the holes are sometimes provided elsewhere the base to receive shipping screws 2| usedwith washers 22. Since typewriter bases vary in width and the distance apart from front to back of said holes in various typewriters varies, it has been My supporting board 18 provides as many sets of holes as are needed to take the various makes of typewriters intended to be fastened to said base. In the drawings I have shown four sets of holes which I have numbered by sets A, B, C and D respectively. For the A typewriter tour A holes are provided through which the shipping screws 2| pass and then enter the base of the typewriter.

Likewise there are four difierent holes for the B typewriter. Likewise for the C typewriter; but two of the 0 holes serve also for the D typewriter as well, so that I have marked two of the holes C-D because they serve for two different typewriters. There are two other D holes besides.

Beyond all of said holes is a border portion 19 on all four sides of the middle portion of said supporting board 18. Said holes A, B, C and D are all directly opposite the space enclosed by the sides Ma of said tube l4. None of said sets of holes are located squarely in the middle or said base. For instance, looking at Figure 2, where either pair of theiront or nearest'A and B holes terminate, there is left a wider portionbetwe'en them and the forward edge of the base than is left at the opposite or rear edge and where the other two pairs of A and B holes terminate. The said wider portion because of thegreater area will serve as the front of said supportingbase when either an A or B typewriter is fastened to said base, so that the keyboard of the typewriter will not project beyond theedge of said board, but will be protected thereby. But where either pair of the C and D holes terminate at the opposite or rear. portion of said board, looking at said Figure2, the wider portion left is between them and the rear edge of said board 18 so that the wider portion of said board l8-for the C and D typewriters will be opposite to the wider portion that serves for said A and B typewriters. 'Said wider portions protect the typewriter keyboard in shipment.

After a typewriter is screwed to said supporting board i8 it is first inserted upside down into'the space enclosed by said tube '14 with said border portion i 9 resting on the edges of said tube I4, as illustrated in' Figure 3 of the drawings. Then the bottom cover pieces H are closed, as illustrated in Figure 4, whereupon the box is turned the other sideup and is ready for shipment.

' Other articles than a typewriter could be so packed and shipped in my box so in using the term typewriter I am not confining 'myinvention to typewriters alone. Adding ijr'nachines, for instance, could be similarly packed.

What I claim is:

l. A carton for typewriters or'the' like comprising an outside box, a'tube of less depth than'and being within and contacting an end extremity or said box when in loading position and having sides all of which are spaced from thesides ofsaid box, filler'me'ans between the sides of said tube asvomio and box and extending to and contacting the inner surfaces of all sides of said box, and a supporting board for a typewriter or the like in said ing an outside box, a tube of less depth than and being within said box having sides all of which are spacedfrom the sides of said box, filler means fitting-snugly-between the sidesOf said box and said tube, and a supporting board for a typewriter or the like 'in said box having holes in a portion thereof through which screws may pass into a typewriter or the like to hold the latter to 'said 'boarmsaid holes being within a portion of said board that is directly opposite the interior space of said tube, said board directly resting upon and supported by said tube sides when'in loading position.

3. A carton for typewriters or the like comprising an outside rectangular box, a tube of less depth than and beingwithin said box having sides all of "which-are spaced substantially equally from the sides-of saidbox, said tube having flanges extending. from the sides of said tube to andin contact with the inner surfaces of all sides-of said box, and a supporting board for a typewriter or the like in said box which is or substantially the same dimensions across as the interior of said box and having provision to attachably receive a typewriter or the like, saidprovision being-within-a portion of-said board that -is directly opposite the interior space of said tube, a portion of said board directly restingupon and supported by said tubesides when-inloading position.

4. A carton for typewriters or the likecomprising an outside. box, a tube of less depth than-and being within and having sides which are spaced from the sides ofsaid box, 'filler means between said tube sides and the sides of saidbox, and a separate supporting-board insaid box having Drovisionto attachably receive a typewriter or the fl ike,-said provision being within a portion of said board that is directly opposite the interior space of said tube, a portion of said board extending laterally beyond the interior space of said tube to substantially the sides of said "box, said board directly resting upon and supported by said tube sides when in loading position.
